How to Create a URL Slug: Free Slug Generator Guide

The slug is the part of a URL that identifies a specific page in a human-readable way. A clean, descriptive slug helps both search engines and visitors understand what a page is about before they even click. Our free slug generator turns any title into a tidy, URL-friendly slug instantly in your browser.

What Is a URL Slug?

A slug is the portion of a URL after the domain that names a specific page. In the address example.com/how-to-create-a-url-slug, the slug is how-to-create-a-url-slug. A good slug is lowercase, uses hyphens to separate words, contains no special characters, and describes the page's content concisely.

Converting a title like "How to Create a URL Slug!" into how-to-create-a-url-slug is called slugifying.

Why Slugs Matter for SEO

Search engines use the URL as one signal of what a page is about. A descriptive slug that includes your target keywords can improve relevance and click-through rates, because people can see at a glance what they will get. Compare these two URLs:

• example.com/post?id=4815 — opaque and meaningless
• example.com/best-running-shoes-2026 — clear and keyword-rich

The second is more useful to readers and more informative to search engines. Clean slugs also look more trustworthy when shared in messages and social posts.

How to Create a Slug Online

1. Paste your title or text into the input box.
2. Choose a separator — hyphen (recommended for SEO), underscore, or dot.
3. Set options like lowercase and a maximum length.
4. Copy the generated slug for your CMS, blog, or framework.

The tool also handles accented characters, converting "café" to "cafe", and strips punctuation automatically. You can even slugify a whole list of titles at once.

What Makes a Good Slug?

• Use hyphens, not underscores. Search engines treat hyphens as word separators; underscores join words together.
• Keep it short. Include the key words and drop filler like "a", "the", and "of" where possible.
• Use lowercase. URLs can be case-sensitive, so consistent lowercase avoids duplicate-URL problems.
• Include your keyword. A slug that reflects the page's main topic reinforces relevance.

Frequently Asked Questions

Is the slug generator free? Yes — it is free, requires no sign-up, and runs entirely in your browser.

Should I use hyphens or underscores in a slug? Hyphens. Search engines treat hyphens as spaces between words, which is better for SEO, while underscores are read as joining words together.

Does it handle accented characters? Yes. Accented letters are converted to their plain equivalents (for example "é" becomes "e") so the slug stays clean and URL-safe.

Can I slugify multiple titles at once? Yes. Paste several lines and the tool generates a slug for each one.
